8GB on the Airs is a completely different issue as these are not marketed as Pro devices.
Consumers place a lot of faith in Apple as a brand so when they go and purchase a "Macbook Pro" they should be able to assume Apple has their back and it's actually going to do what it says on the tin. It's 2023, memory demand is higher than it ever has been and selling a "Pro" computer thats destined to be living on swap so they can try squeeze another $200 out of you is pretty shitty honestly. And it's not like you can just upgrade it, you have to toss it out and get a whole new device.
